Eric Maskin, in his lecture, “An Introduction to Mechanism Design” (Warwick Economics Summit 2014) uses the simple example of a parent wanting to divide a cake between two children. The goal is to divide the cake in such a way that both children are happy. The mechanism could be that one child cuts the cake while the other has first choice of the pieces. The goal of making a “fair division” is known in advance. The mechanism is designed specifically to achieve that goal.

This “one cuts, the other chooses” mechanism is incentive-compatible because it allows both children to achieve their goal, defined as getting at least half the cake.
